a combination of paraffin and carnauba;
and AquaKlean 403, which is a unique
combination of paraffin and polyethylene. AquaKlean products are anion-ic/nonionic aqueous wax emulsions ideally suited for use in latex emulsion systems and can be easily stirred in using
any type of mixing equipment.
According to BYK Chemie Germany,
the matting of high-solids and UV coatings essentially depends on the perfect
incorporation and dispersion of preferably high levels of silica-based matting
agents. However, the use of these high
levels of silica-based matting agents
produces high viscosities, which in turn
create production and application
issues. On the other hand, the more perfect the orientation of matting agents in
finished coating films, the higher the
matting efficiency.
To solve this problem, BYK tailored a
new additive based on Controlled
Polymerization Technology (CPT)—
Disperbyk-2008. Its pigment-affinic
groups have been designed in such a
way that they work equally well on sur-face-treated silicas and on untreated silicas. Special binder-compatible groups
provide compatibility with many different polymers and monomers, and a special modification achieves excellent stabilization of both the finely dispersed silica particles and the inorganic fillers in
the coating. The result is a powerful
matting effect that can even be achieved
with standard matting agents and at
low dosage levels. In addition, the reduction in viscosity provides easier processing properties for matt coatings made
with Disperbyk-2008.
Sun Chemical Performance Pigments
showcased new technologies that will
improve productivity and enhance color
offerings for customers in the consumer
electronics, industrial, waterborne and
architectural coatings markets at the
ECS 2009. The ECS was the launch pad
for SunGEM, a new industrial effect pigment product line from Sun Chemical
that provides ten new shades of high
chroma color with excellent opacity and
European Coatings Congress keynote
presenter, Neal Williams of AkzoNobel
gave a paint maker’s perspective on what
the coatings of tomorrow will look like.
pearlescent luster. SunGEM’s newest
colors will help industrial designers set
new trends and position their products
apart from their competition, according
to Sun.
Sun Chemical also highlighted an
extended natural pearlescent pigment
line under the brand name Sun-Mica.Visitors will be introduced to a full
range of synthetic micas which provide
improved clarity of color combined with
increased pearlescent luster and sparkle.
The new Sun Chemical pearlescent
range offers silver whites, interference
colors and the metallic sheen of golds,
bronzes and russets. The pigments allow
for unique styling and effect opportunities and are available in standard and
weather resistant forms.
International Specialty Products
(ISP) highlighted its offerings in both
biocides and performance additives for
a wide range of coatings applications.
The highlight of ISP’s activities at ECS
2009 was the launch of a new initiative
in support of wood coatings manufacturers called Wood Care Technology.
The initiative features technology and
products to provide protection against
virtually every type of wood degradation. Foremost of these new technologies is ISP’s SunCare line of lignin protection products. Other new products
introduced at ECS include WetCare, an
extreme hydrophobicity technology,
and Fungitrol 400 G, a free-flowing
granular form of the biocide IPBC.
At the 2009 European Coatings
Show (ECS), Cognis unveiled its
newest solutions for the architectural
coatings market. Among the products
presented were new “green” defoamers, highly efficient rheology
modifiers, “green” dispersing agents,
and a natural oil-based coalescent for
water-based architectural paints and
coatings. These solutions fit in with
Cognis’ Greenovating concept that
was launched at the show supporting
paints and coatings manufacturers to
satisfy the consumer trend for products that are both sustainable and
high performing.
Cognis presented Dehydran SE 1, a
polymer emulsion defoamer for high-PVC water-based paints. A new product
for high-end paints in Cognis’ defoamer
range is Dehydran 2293. Cognis’ veg-etable-oil-based defoamer Foamaster
350 was also presented at the ECS.
Cognis introduced two new highly efficient associative thickeners. DSX 3291,
an associative thickener for “green”
water-based coatings, is a pseudoplastic
viscosity builder. DSX 3100 is a highly
efficient ICI builder, which allows for
reduction of KU-builder such as cellulose ethers. Cognis also presented
Hydropalat 216, an efficient and sustainable alternative to polymeric dispersing agents. Other Cognis products
promoted at the ECS included three
“green” dispersing and wetting agents
for pigment pastes and slurries:
Hydropalat 1080, Hydropalat 3204 and
Hydropalat 7003. Lastly, Cognis also
presented Loxanol EFC 300, a VOC-free
coalescent (in accordance with
1999/13/EC or 2004/42/EC), based on
natural resources. CW
